The embodiment relates to a front vehicle cabin vehicle body assembling structure which comprises a cabin longitudinal beam, an A column, a front wheel cover, a vehicle body longitudinal beam and a front floor positioned in a compartment, wherein the cabin longitudinal beam, the A column, the front wheel cover and the vehicle body longitudinal beam are arranged in a matching connection mode, and a reinforcing component is connected between the outer surface edge of the front wheel cover and the bottom of the front floor.

Based on the above overall design concept, an exemplary structure of the front vehicle compartment body assembling structure described in the present embodiment is shown in fig. 1 and 2, and the cabin side member 6 includes a side member inner panel 62 and a side member outer panel 61 that are snap-fit connected and arranged to extend in the longitudinal direction of the vehicle body. Wherein the side member inner panel 62 is closer to the center of the vehicle than the side member outer panel 61. A first flange 63 is formed at an end of the side member outer panel 61 corresponding to the front floor 3, and the nacelle side member 6 is connected to the front floor 3 via the first flange 63 and to the bottom edge of the front wheel house 1 via the top edge of the side member outer panel 61. The a-pillar 4 provided on the vehicle body side member 7 is connected to the other side of the front wheel house 1 with respect to the side connected to the first flange 63, and the vehicle body side member 7 is also connected to the front floor 3. The reinforcement member is connected between the front floor 3 between the a-pillar 4 and the nacelle side member 6 and the front wheel house 1 to improve the connection rigidity between the front floor 3 and the front wheel house 1.

Referring to fig. 3, the front wheel house 1 is connected to the side member outer panel 61 via a second flange 14 formed at the bottom thereof, and the outer surface edge of the front wheel house 1 is connected to the front floor 3 via a reinforcement member. Due to the limitation of the installation space, a bulge protruding outwards towards the inside of the vehicle body is formed in the middle of the front wheel housing 1, and the top of the front wheel housing 1 can be connected with the shock absorber installation frame 8 for installing the shock absorber.

In addition, the outer surface of the front wheel cover 1 adjoining the reinforcement member is configured with a triangular-like profile, which, as shown in fig. 3, is configured as a first profile 13 and a second profile 11 separated by an outwardly protruding bead 12. One corner point of the first profile 13 and the second profile 11 extends towards the nacelle stringer 6 and is fixedly connected to the structure of the nacelle stringer 6. The first molded surface 13 is arranged along the width direction of the vehicle body, the second molded surface 11 is arranged along the height direction of the vehicle body, and the two molded surfaces are arranged in different planes to improve the overall structural rigidity of the front wheel cover 1. With the arrangement, the structural rigidity of the front wheel cover 1 can be enhanced through the connection between the local part and the cabin longitudinal beam 6.

When judging whether the profile is triangle-like, one side of the first profile 13 and the second profile 11 adjacent to the reinforcing rib 12 is simplified into a first side line, one side arranged opposite to the first side line is simplified into a second side line, and a connecting line connected to the front wheel cover 1 corresponding to one end of the first side line and the second side line with a larger distance is called a third side line. If the intersection of the first sideline and the second sideline is arranged corresponding to the intersection of the cabin longitudinal beam 6 and the front wheel cover 1, the profile is considered to be triangle-like. In other words, it is sufficient that the profile has three points resembling a triangle.

The structure of the reinforcing member in this embodiment is shown in fig. 1, 4, 6, and 7, and the reinforcing member is specifically a reinforcing plate 2, and the reinforcing plate 2 constitutes a fixed connection with the a-pillar 4 and the nacelle side member 6 in the direction intersecting the front wheel house 1 to the front floor 3. The cross-sectional area of the reinforcing plate 2 gradually increases from the a-pillar 4 to the nacelle stringer 6 in the direction indicated by the arrow in the figure 1.

The reinforcing plate 2 in this embodiment has a first side 21 fixedly connected to the bottom outer surface of the front wheel house 1, and a connecting leg 22 disposed opposite to the first side 21 and extending toward the front floor 3 to fixedly connect the front floor 3. The first side 21 is specifically a third flange formed on the reinforcing plate 2, and the connecting leg 22 is a fourth flange arranged opposite to the third flange. Two fifth flanges 23 are formed at the large-diameter end of the reinforcing plate 2 to connect the reinforcing plate 2 to the side member inner panel 62, and a sixth flange 24 is formed at the small-diameter end of the reinforcing plate 2 to connect to the a-pillar 4. The first flange 63 of the outer stringer plate 61 is specifically fixed to the large-diameter end of the reinforcing plate 2 to reinforce the connection effect between the reinforcing plate 2 and the nacelle stringer 6.

Further, a connector is connected between the front floor 3 and the a-pillar 4, and a connecting portion connected to the reinforcing plate 2 is formed on the connector. With specific structural reference to fig. 1, 2 and 4, the connecting member in this embodiment is specifically a connecting plate 5, and the connecting member is specifically a seventh flange 51 disposed on the connecting plate 5, and the seventh flange 51 is further configured to be connected to the first flange 63, the front floor 3 and the reinforcing plate 2 located between the fourth flange and the fifth flange 23. An eighth flange 53 connected with the A-pillar 4 and a ninth flange 52 connected with the first flange 63 part on the cabin longitudinal beam 6 are also arranged on the connecting plate 5. Wherein, the simple structure of each turn-ups in this embodiment, the machine-shaping of being convenient for. In addition, by providing the connecting plate 5, the structural rigidity of the front wheel house 1 can be further improved by the a-pillar 4 and the nacelle side member 6.

As shown in fig. 1 and 7, a projection arranged in the vehicle body width direction is formed on the link plate 5 with respect to the front floor 3, and the width of the link plate 5 on the other side of the projection is set gradually larger in the direction indicated by the arrow in fig. 1 from the a-pillar 4 to the cabin side member 6 with respect to the seventh burring 51, thereby facilitating the improvement of the rigidity of the structure.

Furthermore, as shown in fig. 2, the front floor 3 provided corresponding to the reinforcing plate 2 and the connecting plate 5 is provided in a triangular shape, which not only can improve the structural rigidity of the front floor 3, but also facilitates the connection with the cabin stringer 6, the a-pillar 4, and the connecting plate 5, so that the structural rigidity of the front floor 3 can be further improved, and the connection effect between the reinforcing plate 2 and the connecting plate 5 is facilitated.

It is understood that the reinforcing plate 2 in the present embodiment may be only provided to be connected to the nacelle side member 6 or the a-pillar 4, and in this case, the rigidity of the connection between the front wheel house 1 and the front floor 3 may be improved, but the effect of the comprehensive use is also the best effect of connecting the reinforcing plate 2 to both the nacelle side member 6 and the a-pillar 4.

According to the front vehicle cabin vehicle body assembling structure, the reinforcing member is connected between the edge of the outer surface of the front wheel cover 1 and the bottom of the front floor 3, so that the connecting rigidity between the front wheel cover 1 and the front floor 3 is enhanced, the excitation of tires is effectively attenuated, the vibration transmission effect of a power assembly is reduced, and the comfort of a vehicle is improved.
